[edit] Relation to Gauss-Newton / Gradient Descent / Levenberg-Marquardt methods

This topic is somehow related to Gauss-Newton method and Levenberg-Marquardt Method and Gradient descent. None of these requires second derivatives. Gauss-Newton, however, requires an overdetermined system.

The exact relations are not stated in this article. It would be helpful to show different assumptions or what the algorithms do have in common with quasi-Newton-methods.
